Description

A segmented combined bottle sealing structure

technical field

The invention relates to the technical field of food packaging, in particular to a segmented combined bottle sealing structure.

Background technique

Chinese patent 201920393701.4 provides a combined bottle set, and its embodiment 2 introduces a bottle bottom with an inner concave cavity. The top of the inner concave cavity has a hole, and the barrier film covers the opening. The thread is arranged, and when in use, the lower container is rotated to cut the film at the bottom of the upper container to mix the objects in the two containers. The two containers can be freely combined to hold different objects, ready to adjust and drink. But the lower container cannot be used universally with existing beverage bottles of other varieties.

Existing bottles are integrally formed, and the barrier film cannot be replaced with a hard seal. Sealing the barrier film also requires a certain process cost, and the barrier film can only be used once. If the barrier film can be replaced It is a hard seal, which will allow the bottle to be reused, and consumers can prepare the combination of the upper bottle and the lower bottle by themselves.

Contents of the invention

The purpose of the present invention is to provide a segmented combined bottle sealing structure, which can not only combine different condiment packages and beverage packages according to the needs of consumers, but also can be used in common with other existing beverage bottles.

The technical solution of the present invention: a segmented combined bottle sealing structure, including a bottle neck with an external thread segment, a bottle bottom with an inner concave cavity, and a bottle body integrally formed with the bottle neck, the bottle bottom and the bottle body are thermoplastic connected, the inner circumference of the inner cavity is arranged with an internal thread segment, the seal is detachably connected to the top of the inner thread segment, the seal separates the upper space of the bottle bottom from the inner cavity, and the top of the inner thread segment turns toward the center of the inner cavity Folding to form a surrounding piece, the bottom surface of the surrounding piece is attached with a sealing ring, and the inner diameter of the sealing ring is larger than the outer diameter of the top of the external thread segment.

Preferably, the sealing member is a sealing cover or a circular sheet. When the sealing member is a sealing cover, the sealing cover is placed outside the top of the internal thread section; when the sealing member is a circular sheet, the sealing member is embedded on the top of the internal thread section On the inner circumference, an annular groove is arranged on the inner circumference of the top of the internal thread section, and the annular groove is transitionally matched with the sealing element.

Further, the sealing member is also connected to the top of the internal thread section through an adhesive tape.

Further, the sealing ring is made of elastic material, and the sealing ring is arranged in at least one circle.

Optionally, the inner circumference of the shroud is in clearance fit with the outer circumference of the top of the external thread segment.

Preferably, a sealing ring is sleeved on the inner circumference of the internal thread section below the sealing ring, and the inner diameter of the sealing ring is larger than the outer diameter of the top of the external thread section.

Optionally, the bottom end of the internal thread segment is connected to the bottom of the bottle through an arc-shaped cone ring, and the inner diameter of the arc-shaped cone ring from the top end to the bottom end gradually increases, and the inner diameters of the top end and the bottom end of the arc-shaped cone ring are respectively equal to the bottom of the internal thread segment The inner diameter of the end and the inner diameter of the bottom of the bottle, the sealing ring is attached to the inner circumference of the arc-shaped cone ring on the side close to the internal thread section, and the sealing ring and the external thread section are in clearance fit; the bottom end of the external thread section of the bottle neck is from top to bottom A ring of cone rings is arranged in sequence, the sealing ring is in interference fit with the cone ring, and the external thread section and the internal thread section are transitionally fitted; the top of the internal thread section is detachably connected to the sealing member, and the sealing member seals the bottle The space above the bottom is separated from the inner concave cavity.

Further, a protruding ring is arranged under the cone ring, the sealing ring is arranged in at least two layers, and the sealing ring is also interference-fitted with the protruding ring.

Preferably, the length Ln of the internal thread segment is less than the length Lw from the top of the bottle neck to the cone ring, Lw-Ln is less than the sum of the thicknesses of the sealing rings of each layer, and Lw-Ln is greater than the height of the sealing member.

From the above, preferably, the bottom of the bottle is connected to the body of the bottle by means of edible glue adhesion, ultrasonic vibration, or high-temperature thermal fusion above 180°C.

Compared with the prior art, an embodiment of the present invention has the following beneficial effects: 1. When the two bottles are used in combination, the bottleneck of the lower bottle is screwed to the inner cavity of the upper bottle, because the length of the inner thread section The value Ln is less than the length value Lw from the top of the bottle neck to the cone ring, and Lw-Ln is less than the thickness of the sealing ring. When they are close to each other, before the top of the bottle neck touches the seal, the cone ring has already compressed the sealing gasket to make the inner cavity It is isolated by the sealing gasket and the cone ring; 2. When the cone ring completely compresses the sealing gasket, the top of the bottle neck opens the seal, so that the upper space of the bottle bottom communicates with the inner space of the bottle neck; 3. The outer diameter of the cone ring is larger than the bottom of the internal thread section The inner diameter of the end is smaller than the outer diameter of the sealing ring, so that the outer diameter of the cone ring and the inner diameter of the sealing ring have an interference fit; , the sealing ring is not good enough to prevent the upward displacement of the external thread segment; 5. The outer diameter of the convex ring is larger than the outer diameter of the outer thread, smaller than the outer diameter of the cone ring, so that the cone ring moves upwards and passes through the first layer of sealing ring, the second The restored thickness of one layer of sealing ring is in interference fit with the protruding ring to play a sealing role.

Another embodiment of the present invention has the following beneficial effects: the sealing ring is attached to the top of the internal thread section, and the sealing ring is compressed during the upward movement of the bottle neck or sealing ring to play a sealing role. The advantage of this solution is that the lower bottle body does not need special settings.

In the prior art, the bottom of the bottle and the body of the bottle are integrally formed. After the barrier film in the bottle is pierced, the bottle body cannot be used again. In the present invention, the bottom of the bottle and the body of the bottle are changed into a thermoplastic connection. The advantage is that the sealing method of the sealing film can be changed to the sealing of the sealing member. Since the top edge of the neck of the ordinary beverage bottle is relatively round, it is easier to open the sealing member than to pierce the sealing film, and the installation method of the sealing member is also better than that of the sealing film. Thermoplastic packaging is easy, and the seal is connected to the top of the internal thread section by adhesive tape, so that after the consumer opens the seal for the first time, separates the upper and lower bottles, and can also cover the seal again on the top of the internal thread section or Embedded in the inner circumference of the top of the internal thread segment, it can be reused.

The above description is only an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention, it can be implemented according to the contents of the description, and in order to make the above and other purposes, features and advantages of the present invention more obvious and understandable , below in conjunction with the preferred embodiment, and with the accompanying drawings, the detailed description is as follows.
